When day and night are equal around the world (North and South Hemisheres) it is called a equinox. In a year that happens twice, once in the Spring which called a Spring Equinox and once in the Fall which is called a Fall or Autumn Equinox. Spring Equinox occurs on March 21 and Fall or Autumn Equinox occurs September 22
Well, it's importance is relative. First of all, it signifies the first day of Spring in the Northern Hemisphere and the first day of Autumn in the Southern Hemisphere. Equinox means "Equal Night", in other words, both the Northern and Southern Hemispheres receive equal amounts of day time and night time on this day. Does that help?
The sun emits different amounts of energy all the time, however the hemispheres receive equal amounts of SUNLIGHT on the Equinoxes (approx. September 21 and March 21).
The length and experience of season is relevant the latitude that you are at. Both hemispheres are equal in seasons, negating weather, land, water, wind, etc. 45 degrees south is similar to 45 degrees north, just six months apart. As you look more toward the equator the seasons will become more and more similar.
In both hemispheres the Sun rises in the East.
The spring and autumn equinoxes, when day is equal to night in both hemispheres.
Yes they are equal because equinox means equal nights.
Both have 4 sides of equal length
Autumn and Spring are similar in both hemispheres
Yes. They are both equal in length.
The equinox is the point in time where the Sun crosses the equator and there is no tilt to the Earth, thus there are approximately the same number of hours of light and darkness in both hemispheres. The term "equinox" comes from the Latin aequus (equal) and nox (night).
it will fall on the 22nd September 2012 in the Northern Hemisphere. During an equinox the length of day and night in both hemispheres is very much the same . 12 hours day and night. After this date in the northern hemisphere the days will become shorter with the advance of winter
Greenland is in both the Northern and Western Hemispheres
A solstice happens in summer and winter. It is an equinox that happens in autumn, and also in spring. At both equinoxes the length of daytime is about 12 hours, equal to the amount of night time.
